This project implements a secure, transparent, and decentralized voting system using Ethereum Smart Contracts on the Sepolia Test Network. By leveraging blockchain technology, we ensure tamper-proof voting, duplicate voter prevention, and real-time result validation.
In modern elections, fraud, lack of transparency, and vote duplication are major concerns.
This project solves these issues by:
✅ Eliminating vote duplication via unique voter tokens (Driver's License + Address Hash).
✅ Ensuring secure, immutable vote storage on the Ethereum blockchain.
✅ Providing real-time vote verification through smart contract functions.
✅ Preventing unauthorized candidates from being voted for.
The VotingContract.sol smart contract:
- Stores candidate names and votes in the Ethereum blockchain.
- Prevents duplicate voting using a unique voter token (
name + driver's license + address). - Validates candidate names before allowing votes.
- Enables real-time vote tally retrieval.
- The smart contract is deployed on the Sepolia Test Network using Hardhat.
- Voters interact with the contract through a script that executes transactions.
- All transactions are logged on Etherscan for verification.
This project demonstrates a basic Hardhat use case. It includes a sample contract, a test for that contract, and a Hardhat Ignition module for deployment.
Ensure you have the following installed:
- Node.js
- HardHat
- Clone the repository:
git clone <repo-link>
- Navigate to the project directory:
cd path/to/your/project
- Install dependencies:
npm install
- View HardHat commands:
npx hardhat help
- Run tests:
npx hardhat test
- Run tests with gas reporting:
REPORT+GAS=true npx hardhat test
- start a local HardHat node:
npx hardhat node
- Deploy the contract using HardHat Ignition:
npx hardhat ignition deploy ./ignition/modules/Lock.js
- Navigate to the contracts directory:
cd contracts
- Compile contracts
npx hardhat compile
To run the smart contract script:
node ./scripts/smartcontractconnect.js
- Deploy to a local HardHat node:
npx hardhat run ./scripts/deploy.js --network localhost
- Deploy to a Sepolia test network:
npx hardhat run scripts/deploy.js --network sepolia
- In HardHat version 6.6.2: We were able to deploy contracts successfully.
- In HardHat version 5.7.2: We can run tests.
- 🛡️ Enhanced security: Implement Zero-Knowledge Proofs (ZKPs) for anonymous voting.
- 🗳️ Multi-phase elections: Support multi-round voting with different categories.
- 📊 Real-time dashboard: Develop a web interface for voters to track votes.
- 🌎 Global scalability: Expand cross-chain compatibility with multiple blockchains.
- 🔗 Government adoption: Collaborate with institutions for real-world implementation.
